双杆菌

In the development of probiotic products, different species of Lactobacilli and Bifidobacteria are selected according to their abilities to produce yogurt, to survive passage through the digestive tract, and to establish themselves in their new environment by outcompeting potentially unfriendly microbes for space and nutrients.

Subclones of the hybrid 741 took on a high insect-resistant identity to the larvae of leaf pests such as Clostera anachoreta Fabricius, Lymantria dispar Linnacus, Hyphantria cunea Drury ect., and the mean death rate of the grubs were all above the 85%, furthermore, the grubs' growth which survived could be restrained and the growth rate was reduced so that they couldn't tie cocoons as the usual.

项目简介：转双抗虫基因741杨是将部分改造BtCryIAc 基因与慈菇蛋白酶抑制剂基因，通过农杆菌介导法转化了优良白杨杂种741杨，并获得了一批具有高抗虫性无性系，对舞毒蛾和杨扇舟蛾，美国白蛾等鳞翅目幼虫死亡率达85%以上，并能抑制存活幼虫的发育，使其不能正常化蛹。

Methods Expression plasmid was constructed with DNA recombi nant technique.

Thecabbagy produce by such proedure can be kept at nounal tewperation for 30 days withvacuum package, the living bimobacterium adolescentis cells of which are above 10个/g

液体菌种的接种量为2％。用此工艺制得的成品酸菜经真空包装后在常温下贮藏30天，其中的青春双歧杆菌数不少于10个／g。

The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.

摘 要：分离出菠菜甜菜碱醛脱氢酶基因构建成由CaMV35S驱动的双元植物表达载体pBSB，农杆菌菌株LBA4404携带该载体转化棉花，获得转基因棉花植株。65株转基因植株经过PCR筛选、Southern blotting分析证明有45株为成功的转化株，外源基因已经被整合到棉花的染色体组中，并以单拷贝插入居多。

The technology for production of sugarless carrot yoghurt was studied in the paper.

研究无糖双歧杆菌胡萝卜酸奶的工艺。

At last, the effects of JA on the bile salt resistance of Bifidobacteria were studied.The test proved that:Deoxycholic acid Na-Salt had intensely toxical action on Blm and Bbm;Adding glucose and fructose in media could decrease the lexical action on Bbm.but inulinand JAP had not apparent effect.

初步研究了菊芋对双歧杆菌的胆盐耐受性的影响，实验表明，脱氧胆酸钠盐对Blm和Bbm有一定毒性作用；在培养基中补充一定量的葡萄糖和果糖可以改善Bbm的胆盐耐受性，而菊糖和菊芋粉对提高Blm和Bbm的胆盐耐受性没有明显作用。

Proteomic comparison of glucose- and lactose-grown cells revealed that lactose and glucose were catabolized via the same degradation pathway, and the rate of glucose assimilation was higher than that of lactose.

长双歧杆菌NCC2705在乳糖中生长快于葡萄糖，它们的降解途径是相同的；转醛缩酶和丙酮酸激酶发生了翻译后修饰作用，推测转醛缩酶在43T和47S发生了磷酸化，而丙酮酸激酶在65S发生了磷酸化。

Then, low-dose broad-spectrum antibiotic was prophylactic used to prevent secondary infections. Drugs addressing gastrointestinal bacterial flora or constipating remedy, such as Bifidobiogen-Livzon, Smecta and loperamide were used to regulate the gastrointestinal bacterial flora and antidiarrheal.

d，连续静滴14 d；预防性应用小剂量广谱抗生素，避免继发性感染；应用调节胃肠道菌群的药物和止泻药物：双歧杆菌活菌制剂、蒙脱石散剂、盐酸洛哌丁胺胶囊等；调节免疫抑制剂的用量及对症支持疗法。

Wort is prepared by lixiviated saccharification, filtered,hops added,boiled and Co-fermented by Bifidobacterium bifidum and Saccharomyces cerevisiae, and making antisepsis and centrifugation.
